Slot Selection Rules for Origin 2000 Deskside and SGI 2200 Servers
Each node board accommodates a maximum of 3 TPU cards. In general, if an server has
a node board in slot N1 or N3 with BaseIO in XIO slot 1, then XIO slots 2–6 are available
(shown in Figure 2). If it has a node board in slot N2 or N4, XIO slots 7–12 are available.
If a module has at least two node boards, one in N1 or N3 and one in N2 or N4, then XIO
slots 2–12 are available. (For servers with 2 or more nodes, refer to Table 3 for the
recommended slot order of installation.)
